I've just tried to create a couple of DVDs using Mytharchive. Using the
menus and after trying three DVD players, I'm yet to find one that seems
to work properly. I'll put the specifics in another message later when
I've noted everything down, but for now my problem is with a movie I
recorded from TV and am trying to archive to DVD without any menu.
Before making the DVD, I went through and removed all commercials, then
let Mythtranscode remove them using the lossless mpeg 2 feature
(original recording was from DVB-T).
I then proceeded to create a DVD with no menu and the LP re-encoding
profile. Everything seemed to go smoothly until I tested the DVD and
found the last 10 minutes or so to be missing, ie, the DVD players claim
that the disc is about 10 minutes shorter than the original recording
(with commercials removed). The last 10 minutes play fine in the Myth
recording.
Looking at the logs created by Mythburn, I see thousands of lines of:
video PTS inconsistent: 2:17:06.940 2:17:06.940 2:17:07.180

Then there is:

2:17:07.000 diff: 0:00:00.240
and the log continues until the end of the recording, but now (like
above), every couple of lines there are two columns of time rather than
the 4 that always existed before the error. The interesting thing is
that the DVD player claims that the length of the movie is 2:17:06,
which is suspiciously close to the "Wrong audio frame size: 1057" error.
Later on in the next step I see:
at 2556MB, 1 PGCS^MSTAT: VOBU 17328 at 2558MB, 1 PGCS^MSTAT: VOBU 17344
at 2560MB, 1 PGCS^MSTAT: VOBU 17360 at 2563MB, 1 PGCS
STAT: VOBU 17376 at 2566MB, 1 PGCS^M**ERROR: [mplex] Can't find next AC3
frame: @ 197424384 we have 4d1c - broken bit-stream?
It then goes on to write the DVD without any trouble.
Now from reading the logs, I presume that there was some corruption in
the audio stream resulting the recording being cut short. Is there any
way around this? I thought that the mpeg2 transcode would have fixed
this up?
I'm using SVN rev 11460.
